Data from the official Aqara and Ring sites.
2026 verdict
The Aqara Doorbell Camera G400 (Wired) rates higher than the Ring Battery Doorbell (2nd Gen) and pulls ahead on connectivity, smart home integrations, local storage and the number of alert types it supports.
The Ring Battery Doorbell (2nd Gen) answers with the lower price, Ring's Retinal 2K sensor with 6x enhanced zoom, and a genuinely wire-free install, though its battery is built in and has to be unmounted from the wall to recharge. Both share a one-year warranty, customizable motion zones and preset automatic replies. Choose the Aqara Doorbell Camera G400 (Wired) for the better rating, richer integrations and local recording with no subscription; choose the Ring Battery Doorbell (2nd Gen) if a lower entry price and Ring's 2K sensor matter more than local storage.
